A non-ferrous non-reactive precast shoreline restoration and retention solution may include at least one generally hexagonal structure including a body having a first end opposite a second end. The body may define a passage from the first end to the second end and at least one aperture defined in the side or sides of the body. The at least one aperture may be constructed and arranged to allow fluid flow through the passage of the at least one generally hexagonal structure. In this way, at least one or a plurality of non-ferrous non-reactive precast shoreline restoration solution may reduce erosion of shoreline and reef by functioning as a wave break in an aquatic operating environment.

A module for an artificial reef is substantially in the shape of a continuous arch and is formed as a skeletal framework comprising a plurality of spaced apart transverse beams that each define a portion of the arch, and a plurality of longitudinal beams attached to the transverse beams and extending the length of the arch. The longitudinal beams provide a barrier to waves when one or more modules are anchored to the sea floor. The module is additionally usable as an electrified reef to accelerate mineral deposits on the beams that encourages marine life and increases the effectiveness of the wave barrier.

An interlocking modular smart seawall diversion and recreation system provides step-shaped diverter sections arranged side-by-side along a shoreline. The diverter sections slope from a base end up towards an upper end. To break kinetic energy of waves, and divert waves, the diverter sections form steps with curved risers and horizontal treads. The system forms a diversion path for the waves that reach the upper end of the modular walls and recirculate the wave energy back to divertor chamber and natural environment. Foundation pilings project into the ground and extend up to support the wall sections. The bottom end of foundation pilings terminates at sheared attachments having a tapered cross section and an edge for securely anchoring into the ground. A platform atop the diverter sections provides a pathway; a lighted platform for recreational activities; and transparent skylight portals for observing aquatic wildlife in water below and creating an indigenous ecosystem.

The invention relates to an underwater modular structure comprising a plurality of modules, at least one connector that interlocks the plurality of modules and a labyrinth defined by contours of at least the plurality of modules. Each module of the underwater modular structure comprises at least one connector insertion opening that is configured to receive a connector therethrough. Further, the at least one connector is an elongate member arranged through at least one connector insertion opening of each of the plurality of modules thereby interlocking the plurality of modules. The labyrinth of such underwater modular structure may at least in part be defined by outer and/or inner contours of the plurality of modules. The invention also relates to a module of or for an underwater modular structure according to the invention. Finally, the invention relates to a method of constructing an underwater modular structure, the method comprising the steps of sinking a plurality of modules to a seabed, each module comprising at least one connector insertion opening, and interlocking the plurality of modules with at least one connector that is an elongate member, by arranging the at least one connector through at least one connector insertion opening of each of the plurality of modules, to form a labyrinth defined by contours of at least the plurality of modules. Such method may further comprise the step of filling at least part of the underwater modular structure with a filler.

Portable and interchangeable marine tiles, marine pods and tanks are disclosed. The marine tile typically contains a first face, a second face, and one or more sites for supporting one or more marine organisms, such as coral, and. may contain a tracking device. The marine pod typically contains a first panel having a first slit and a second panel having a second slit. The first panel and the second panel can be interlocked via sliding the first slit into the second slit. The marine pod can have one or more marine tiles attached thereto. The marine tank typically contains one or more coral reef organisms. Water can be pumped into and through the marine tank to flow in the form of a river stream. Typically, the flow of the seawater is controlled such that a consistent temperature is maintained in the marine tank.

Compositions for making native-like marine structures are provided. The compositions include materials, typically a limestone and/or ceramic composite, for 3D printing of marine structures. Environmentally-friendly 3D printing and coating methods are also provided. The methods can be used to print structures/objects composed of a 3D printing material such as the compositions described herein, and/or coat formed structures/objects with an adhesive, such as a peptide-based bioorganic adhesive. Compositions and methods for supporting the attachment and growth of marine organisms such as coral to a substrate are also provided. The compositions contain one or more self-assembling peptides suitable for use as bioorganic adhesives. The peptide compositions are suitable for adhesive applications in the marine environment such as supporting coral growth and restoration. Methods of using the peptide-based adhesive compositions are also provided.

A device designed to stabilize a shoreline which helps to prevent erosion, provides and supports a place for aquatic life to thrive, and is made from a plurality of primarily calcium carbonate material sourced from living creatures and is cemented together using a commercially available cement or bio-cement material.

The invention belongs to ecological revetments in the technical field of river ecology, which particularly involves an ecological revetment to regulate wandering rivers. The ecological revetment is composed of porous concrete-piles, ecological connecting-plates, an ecological viewing-corridor and a slope green-belt. The ecological landscape-corridor and anchor rod are placed on the upper and middle parts of the pile structure, respectively. In virtue of the innovative structure, the ecological revetment will strengthen the revetment structure, reduce the revetment settlement, prevent the revetment from moving, and enhance the overall stability of the revetment project. The ecological holes exist on the ecological connecting-plates, which is beneficial to the exchange of material and energy from the river course and the bank slope, and the holes could greatly enhance the self-cleaning capacity of the water body. Not only do the plants on the ecological viewing-corridor provide the habitats for the organisms, but also green the revetment.

Disclosed is an artificial reef molded from a mixture of environmentally friendly homogenized organic and inorganic materials, cement, and 5 aggregates of sand and gravel to form thereon an artificial reef such as reef buds, reef plates, reef honeycombs and other reef structures.
